I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101 after rebooting.

The installation starts, and after a couple  restarts, it says:

" Attempting to recover installation "

" Undoing changes made to your computer "

And then I am greeted with error 0xc1900101 on Windows Update.

Windows for home | Windows 11 | Windows update

Dear Ramesh,

Thank you for your assistance, you were really helpful.

At a point my pc touch screen stopped responding during the many installation attempts, so didn't know what I had done to cause this. then I decided to clean install, so i chose not to keep my files and settings and it worked.

    Ramesh, would you be willing to take a look at my log and farbar files. I've tried both the 24H2 update and installing from the ISO numerous times, including many of the "self-help" suggestions available on the net such as clean boot, disabling signature verification, and a few others, all with the same failed result.

    My files are at 24H2 Files.zip

    Thank you for any assistance you can provide.

    Alan

    Hi Alan,

    Please see if you can enable Memory integrity. If it lists incompatible drivers (e.g., PxHlpa64.sys), we need to eliminate such drivers.

    Victory! Thanks for the quick and able assistance. Sadly, my logitech webcam is the victim of the purge.
